Abstract
The utility model discloses a kind of safety injectors; including core bar, piston, housing, needle holder and syringe needle; housing is sleeved on the periphery of core bar, and piston is arranged in housing, and piston is arranged in the front end of core bar; needle holder is arranged in the front end of housing; there are two locating slots, needle holder to be connect with syringe needle by connector for setting in needle holder, and a magnet layer is arranged in the inner wall of connector; two and the matched scalable salient point of locating slot are arranged in the outer wall of connector, and the outer surface of syringe needle coats one layer of protective case.The utility model is compact-sized simple, can perseveration, during replacing syringe needle, can ensure user not by needlestick injuries, and replacement action is very convenient, ensure that syringe needle will not stab medical staff, substantially increases safety coefficient.
Description
Technical field
The utility model is related to medical instruments fields, more particularly to a kind of safety injector.
Background technology
The syringe of general curative is typically equipped with a sheath, in syringe before use, the sheath is set in needle portion
In on needle stand, syringe needle is coated.The injection operation of medical staff in practice, sheath is removed in nursing station, carry out first
Medicament is extracted, then it is patient injection to send to ward, during this section, to avoid the risk for recovering sheath by needlestick injuries, or peace
Full sheath limits the job requirements that can not be recovered for first use, and sheath is separately placed on one side and does not use, and syringe needle is caused to present
Naked state, in this way, also opposite improve the probability of needlestick injuries people or syringe needle by outside contamination.Moreover, the needle of the prior art
Head is connect with the mode of needle holder generally use clamping, accordingly, there exist connection inconvenience, is possible in installation process to be wounded by stabbing
Risk.
Invention content
The utility model provides a kind of safety injector, can solve completely to overcome the shortcomings of above-mentioned technical problem
Certainly above-mentioned technical problem.
The technical solution for solving above-mentioned technical problem is as follows：
A kind of safety injector, including core bar, piston, housing, needle holder and syringe needle, housing are sleeved on the periphery of core bar, living
Plug is arranged in housing, and piston is arranged in the front end of core bar, and needle holder is arranged on the front end of housing, needle holder there are two settings
Locating slot, needle holder are connect by connector with syringe needle, and a magnet layer, the outer wall setting two of connector is arranged in the inner wall of connector
The outer surface of a and matched scalable salient point of locating slot, syringe needle coats one layer of protective case.
It further says, the outer surface of the housing is provided with graduated scale.
It further says, the rear end of housing is provided with extension, and a block is socketed on the extension.
Furthermore, the core bar is cylindrical structure.
The utility model is compact-sized simple, can perseveration, during replacing syringe needle, can ensure user not by
Needlestick injuries, and replacement action is very convenient, passes through scalable salient point and the locating slot in needle holder being arranged outside connector
The magnet layer of connection, the setting of connector inner wall can easily attract syringe needle, and very securely, due to the external setting of syringe needle
One protective case, ensure that syringe needle will not stab medical staff, substantially increases safety coefficient, can also prevent syringe needle by extraneous dirty
Dye.Core bar uses cylindrical structure, during pushing and pulling core bar, can guarantee the concentricity of core bar and housing, prevents the curved of core bar
It is bent.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1 is core bar, and 2 be housing, and 3 be piston, and 4 be syringe needle, and 5 be needle holder, and 6 be connector, and 7 be protective case, 8
It is extension for scalable salient point, 9,10 be block.
Specific implementation mode
Safety injector as shown in Figure 1, including core bar 1, piston 3, housing 2, needle holder 5 and syringe needle 4, housing 2 are sleeved on
The periphery of core bar 1, piston 3 are arranged in housing 2, and piston 3 is arranged in the front end of core bar 1, and needle holder 5 is arranged before housing 2
It holds, setting is there are two locating slot (nothing is shown in figure) in needle holder 5, and needle holder 5 is connect by connector 6 with syringe needle 4, connector
6 inner wall is arranged a magnet layer, and the outer wall of connector 6 is arranged two and the matched scalable salient point 8 of locating slot, syringe needle 4 it is outer
Surface coats one layer of protective case 11.The outer surface of housing 2 is provided with graduated scale (nothing is shown in figure).The rear end of housing 2 is arranged
There is extension 9, a block 10 is socketed on the extension 9.The core bar 1 is cylindrical structure.
The utility model is compact-sized simple, can perseveration, during replacing syringe needle, can ensure user not by
Needlestick injuries, and replacement action is very convenient, passes through scalable salient point and the locating slot in needle holder being arranged outside connector
The magnet layer of connection, the setting of connector inner wall can easily attract syringe needle, and very securely, due to the external setting of syringe needle
One protective case, ensure that syringe needle will not stab medical staff, substantially increases safety coefficient, can also prevent syringe needle by extraneous dirty
Dye.Core bar uses cylindrical structure, during pushing and pulling core bar, can guarantee the concentricity of core bar and housing, prevents the curved of core bar
It is bent.
The above is only presently preferred embodiments of the present invention, not does limitation in any form to the present invention, it is every according to
According to any simple modification, equivalent variations made by above example, each falling within the guarantor of the present invention in the technical spirit of the present invention
Within the scope of shield.
